Any files that are encrypted with LockBit (ACBD, LockBit 2.0) Ransomware will have an .abcd, .lockbit
.lock2bits
or .luckyday extension appended to the end of the encrypted data filename and typically will leave files (ransom notes) named Restore-My-Files.txt, Recovery.txt as explained here by Amigo-A (Andrew Ivanov). 
 
Any files that are encrypted with the original LockBit 3.0 (LockBit Black) typically will have TWO strings of random.random characters appended to the end of the encrypted data file and leave files (ransom notes) named with the same second string [random characters].README.txt, [random characters].bmp as explained here.
 
 
 
hi. help return the files. Is there a free decryption for this ransomware?

Hello

 

You will need attach to message HERE 2-3 encrypted files (different formats - doc, png, jpg) and the original note file.
You can use external file hosting services and give ME a link to download encrypted files and other files.

Is .ABCD the complete extension appended to the end of your encrypted data file names? 

 

Did you find any ransom notes and if so, what is the actual name of the ransom note?
Can you provide (copy & paste) the ransom note contents?
Did the cyber-criminals provide an email address to send payment to? If so, what is the email address?
 

Did you submit (upload) samples of encrypted files, ransom notes and any contact email addresses or hyperlinks provided by the cyber-criminals to ID Ransomware (IDR) or Emsisoft Website for assistance with identification and confirmation of the infection? ID Ransomware can identify ransomwares which adds a prefix instead of an extension and more accurately identifies ransomwares by filemarkers if applicable so try that first. Uploading both encrypted files and ransom notes together along with any contact email addresses or hyperlinks provided by the criminals gives a more positive match with identification and helps to avoid false detections.

Please provide a link to the ID Ransomware results.

It looks new Ransomware and but it is very similar to Jamper Ransomware.
We need more information.
 
I wrote you what needs to be done immediately.
Do not run cleaning programs or antivirus tools. This can be done later when the files for analysis are collected.

My company was struck by these ransomware. They encrypted the entire network - 17 computers. We didn’t find a free decryptor and we had to pay money to ransomware

Since you have a working decrypter, you can zip and submit it here with a link to this topic along with a few encrypted files, the private key and anything else the malware writers provided. Our crypto malware experts may be able to get some information to exploit by analyzing it further. While the decryption tool is not as good as analyzing the ransomware itself, it may still provide our experts some information about the encryption format used by the malware developers.
